A few people have mentioned here that they thought Thor didn't react appropriately to Frigga's death. What should he have done differently?

Spoiler!!! Click to Read!:

-He ran in and blasted Malekith in the face, and hurled Mjolnir at them until they got away and turned invisible.
-He mourned at Frigga's funeral. (Loki got his own reaction scene because he wasn't present at either Frigga's death or her funeral, as Thor was).
-He had a discussion w/ Loki on the flying ship that he loved her just as much as Loki did, and that she wouldn't want them to fight.

What else should he have done to please people? Frazzle his hair and stomp on grapes, like Loki did?

Honestly, I have no clue. There was plenty of time devoted to it. If anything, I'd argue there was too much time devoted to it as we, the audience, simply had no investment in the character.
